I converted my IRA's to a Roth Conversion IRA account in 1998. I was told then that the Roth conversion accounts and the Roth contributory accounts had to be separate. Now, I understand that this may have been changed and I can contribute yearly amounts to my Roth Conversion account. I would like to know if this is true so I can make my 1998 contribution into just one account.

You can make the annual contribution to the same Roth account.
